RECIPEOCATING-PLUG FAUCET.

Application filed June 18, 1921." Serial 110 478553 To all whom. it mayconcern Be'it known that I, HENRY G. CORDLEY, a citizen of the UnitedStates, residing at Glen Ridge, in the county of Essex, State ofNewJersey, have invented certain new and useful Improvements inReciprocating- Plug-Faucets, of which the following is a description,reference being had to the accompanying drawings, forming a part hereof.4

My invention relates to faucets of the reciprocating plug, springactu'ated type and has for its object to provide a faucet of this typewhich will be simple and inexpensive in construction, will beself-closing and at the same time adapted to be held open if desired,will be easily taken apart for cleaning or replacement of'wornparts,.will not readily get out of order and :will be effective inoperation.

With the above described objects, and other objects hereinafterexplained'in view my invention consists in the construction andcombination of elements hereinafter, de scribed and claimed.

Referring to the drawings; H

Figure 1 is a central vertical longitudinal sectional view of a faucetembodying my invention, showing the faucet closed. V

Figure 2 is a view similar to Figure 1 but showing the faucet open.

Figure 3 is a side view of a portion of the means for opening the faucetand holding it open, the parts being shown in tlieposition which theyassume when thefaucet is closed. M

Figure 4 is a view similar to Figure 3 butshowing-the parts in theposition which they assume when the faucet is to be held open. I

Figure 5 is an end view of thefaucet.

Figures '6 and 7 are views showing the packing ring in vertical seetionand in end view respectively.

In the drawings 1 indicates'the inner member of the faucet casingconsisting of a piece of straight tubing serewthreaded in its rearportion as shown at 2 to receive a nut 3 on the outside of the wall 4 ofthe tank from whichliquid is to be drawn, and a nut 5 on the inside ofthe wall 4, these nuts bearing against gaskets 6 and Z respectively, ofrubber or other material adapted to be compressed to prevent leakageabout the tube 1 where it passes through the' usual faucet opening inthe'wall 4-.

8 indicates the outer member of the faucet casing also .formed of astraight piece of tubing, having an abutment 9 formed at its inner endadapted to fit over-and be secured on the forward end'of the innercasing member 1. Near'its rear-end this'outer casing member has formedin its under side a discharge opening 10, and it is internallyscrewthreaded at its forward end as shown atll. I V.

l2 indicates a cylindrical plug valve which fits withinand is adapted toreciprocate in the outer casing member 8. This plug valve is carriedbyavalve rod 13 'the inner end of whichis preferably connected by a balland socket joint with the. plugasshown. This valve rod extends throughacentral opening in a cap 14 which is externally screwthreaded at itsinner end to engage the screwthread ll'of the outer casingmember 8, andcarries onitsouter end a double cam by means of which the plugvalve isdrawn outward when the valve rod is rotated as hereinafter described.

The. double earn consists of fixed cams 25 and 26 formed in acylindrical shell extending'forward from the head of the caplet, the twocams being identical in shapelbut oppositely arranged with referencetothe axis ofthevcap, each extending from a point 27 near the head of thecap to a point 28 at 'a distance from the head of. the cap correspondingtothe distance through which the plug valve is to be .moved. The valve13od 13 is provided on:opposite sides -with radially extending ,lugs and31 the rear faces of which, that is the faces toward the cap 14, areflat and in a plane at right angles to the axis of the valve rod.Attheir outer points, 28 thecams are out off in a plane at right anglesto the axis of the cap so as to form ledges 32 on which the lugs 30 and31 carried by the valve rod may rest and from which they will not tendto slip off. From the ends of these ledges 32 the shell in which thecams are formed iscut away on lines parallel with the axis of the cap tothe points 27.

The plug 12 has formed in its outer end an annular recess 17 to receivethe inner portion of an expansion coiled spring 18 the outer portion ofwhich is received in the inner end of the'cap 14, the spring thusbearing at one end against the plug 12 and at the other end against theheadofthe cap 1 1 and acting to separate the plug andcap, "forcing thecap inward against its seat.

On the valve seat i ormedby, the inner end of the innerfcasingmemberljis arranged a:

' packing ring 20 which may be oii wood or any Y ner casing member. Whenitis desired to remove a packlng ring all that is necessary,

1 the cap l lbeing unscrewed. and removed with the ping 12 ;is to insertrod of suitable diameter through the rear end of the inner casing member1 and push the packing ring out through the outer casing member, or, by

means of a suitably hooked instrument, to reach in through the outer casng member n afte gag ng s ook wi he Il11g'2' 9,

and draw itou't with the ring 20,

v rod' 13 with the plug 12, as shown; is provided'byiorming centrally ofthe, outer end of the pluga recess adapted to receive the ball shapedhead 36 formed on the inner end of the valve rod. and forcing the wallsof the i v recess; between itand the annular it may be rotated;

against the packing ring 20 and closing the recess; 17, inward toenclose the head. 7 The valve rod13is provided at its outer orforwardendwith a cross WVhen it is desired to open the faucet the partsbeing in the position in which'they are shown in Figure 1,"with' thelugs 30 "and31 resting at the points 27 and the spring 18'be ing inexpanded position forcing the plug 12 discharge'opening' 10, byrotatingthe valve rod 13 by meansof the crossbar 37 the lugs 30 and 31are caused to travel outwardon the cams 25 and 2 6 drawing the plug 12out; 7

Ward against the resistance of the spring 18 away from its 'seat andaway fromthe'dispiece 37 V by which charge opening 10, permitting liquidto How freely. When the lugs 30 and 81' reach the ledges 32the plug willbe fnllywithdrawn.

If ityisdesired'to'have the faucet remain open the lugs 80 and" 31 willbe allowed to rest on the ledges froinwhich theywill not readilys lipoff their under or'rear faces being in a planeat right angles to theaxisof the ledges which are alsoin a plane at right to hold the lugsagainst the ledges. When itis desired'to have the faucetclose, the valvend e e edtili'e r direct on su e e t y to v th lug Ofi llel g If e-va ved is r ta o he rig t th ug il pas over theedges of the ledges andloedmawn rearward at once tov the points- 27, the; plug angles totheaxis and the spring 18 acting being forced rearward against-its seat.If

Having thus described my invention what I claim is; r 7 7 v In areciprocatingplugfaucet, the combination with an outer casing memberhaving Y The ball and socket-connection of the valve a valveseat at its:rear'end and 'a discharge opening-in its side, of a plug valvelfittingsa d outer. cas ng member andadapted to re ciprocatetherein and to closethedischarge opening, a cap secured on the outer end of from the capaledge'ina :plane at right a-ngles with the axis of casing, andoppositely arranged radially extending lugs carried by" the valve rod inposition ,tobear against said cams, each of said lugs having its innerface fiat 'and'in a -plane at right angles with the axis of thevalve rodadaptd to heldf-"onsaid ledges by said expansion spring.

In testimony whereof I affix my signature this thirteenth day'of June1921.
